I've wanted for awhile to write a 24H Puzzle Competition round and simply not had the time to put it all together, particularly with all the other things I am doing. Fortunately Team USA, lead by Palmer Mebane and helped by Wei-Hwa Huang, got one together this year and I contributed 25% of the puzzles. With three different authors and three different perspectives on difficulties, the competition balance of the set was clearly too hard. But the puzzles were in my opinion uniformly great. I'll be posting mine over the next few weeks.
Palmer has already posted all of his.
Our 24H round looks a bit like my first Decathlon structure - 8 genres, with 2 classic and 1 less common style/variation. I took on the object placement and number placement genres. Here is my "24" themed Battleship (20 points - between easy and medium)
Rules:
Locate the indicated fleet in the grid. Each segment of a ship occupies a single cell. Ships can be rotated. Ships do not touch each other, even diagonally. Some ship segments, or sea cells without any ship segments, are given in the grid. The numbers on the right and bottom edges of the grid reveal the number of ship segments in that row or column.
